DTC Logic

INFOID:0000000010432213

DTC DETECTION LOGIC 

NOTE:
Sunload sensor may register a malfunction when indoors, at dusk, or at other times when light is insufficient.
When performing the diagnosis indoors, use a lamp (60 W or more) that is pointed at the sunload sensor.

POSSIBLE CAUSE

[CIRCUIT SHORT TO GROUND]

• Sunload sensor
• A/C auto amp.
• Harness or connectors (The sensor circuit is shorted to ground.)

[CIRC SHORT TO BATT OR OPEN]

• Sunload sensor
• A/C auto amp.
• Harness or connectors (The sensor circuit is open or shorted to battery.)

FAIL-SAFE

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1.

Turn ignition switch ON.

2.

Select “Self Diagnostic Result” mode of “HVAC” using CONSULT.

3.

Check DTC.

Is DTC detected?

YES

>> Refer to 

HAC-90, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010432214

1.

CHECK SUNLOAD SENSOR SIGNAL
